Qt Framework

The complete software development framework

The Qt framework contains a comprehensive set of highly intuitive and modularized C++ library classes and is loaded with APIs to simplify your application development. Qt produces highly readable, easily maintainable and reusable code with high runtime performance and small footprint – and it’s cross-platform.

Qt ESSENTIALS

Making true cross-platform possible

Qt Essentials define the foundation of Qt on all platforms. They are available on all supported development platforms and on the tested target platforms.

Qt Core

Core non-graphical classes used by other modules.

Qt GUI

Base classes for graphical user interface components. Includes OpenGL.

Qt Multimedia

Classes for audio, video, radio and camera functionality.

Qt Network

Classes to make network programming easier and more portable.

Qt Quick

A declarative framework for building highly dynamic applications with custom user interfaces.

Qt SQL

Classes for database integration using SQL.

Qt ADD-ONS

The right add-ons
for the right task

These special-purpose modules may only be available on some development platform. Many add-on modules are either feature-complete and exist for backward compatibility or are only applicable to certain platforms.

Qt OpenGL

OpenGL support classes. Deprecated in favor of the QOpenGL classes in the Qt GUI module.

Qt Wayland Compositor

Provides a framework to develop a Wayland compositor.

Qt Sensors

Provides access to sensor hardware and motion gesture recognition.

Qt WebView

Displays web content in a QML application by using APIs native to the platform, without the need to include a full web browser stack.

Qt Safe Renderer

Provides a UI rendering component that can be used to render safety-critical items, such as warning indicators, in functional safety systems.

Qt SCXML

Provides classes and tools for creating state machines from SCXML files and embedding them in applications.
